Simulator for Automotive Applications

This design is a cranking simulator which generates three different cranking pulses to test automotive systems up to 50W. A microcontroller sets the output voltage of a synchronous buck in the range of 2-15V accordingly to the programmed curves. Output current is in the range of 3.3-25A. It is a complete system and all the information necessary to build the device is available.

  • Device has transient protection that withstands up to 62V spikes on Vin and enables design flexibility
  • Device responds almost immediately to line transients with better than 1% regulation on output
  • Voltage tracking reduces external components saving board space
  • Logic device supports live insertion, partial power down mode and back drive protection
  • Losses minimized in power application
